When 2 objects have the same charge they do this to each other
What is push away or repel
This part of an atom has a positive charge
This is the name for the top part of a transverse wave
What is the peak
These are the two main types of mechanical waves
What is transverse and longitudinal
Em waves are put into their categories based on their what
What is wavelength
This force increases when the mass of an object increases
What is gravitational force
This part of an atom has a negative charge
What is an electron
What is energy
The matter that a mechanical wave is traveling through is called a what
What is a medium
This EM wave has the highest wavelength
Radio waves
This force happens when electrons move from one object to another due to friction
What is electrostatic force
How two positive charges react to eachother
what is they repel
What is the Trough
These are the two main properties of sound
what is pitch and volume
This EM wave is best for detecting heat, like forest fires
What is Infared Light
This force is created becuase all the atoms in a substance are so aligned and close together that all the electrons start spinning in the same direction creating an electric current and causing the item to develope poles
What is Magnetism
An object that is gaining electrons, has what charge?
Negative charge
This part of a wave is measured from peak to peak
wavelength
A loud sound has this type of amplitude
HIGH amplitude
This type of material allows SOME light through.
What is transparent
These Two Factors can increase gravitational force
What is mass and distance
When atoms spin in the same direction it causes this type of current
This happens to energy when wavelength increases
What is Energy decreases
A high-pitched sound has this type of frequency.
High Frequency
An electromagnetic wave is composed of these two fields
What is Electric field and Magnetic field
